SHOCK-ABSORBER AND SUPPLEMENTARY srnme.

To all whom it may concern v r Be 'it knownthat 1, JOHN A. Memoir, a

citizen of the United States, residing at Princeton, in the county of Gibson and 6 State of Indiana, have invented certain new and useful Improvements in Shock-Absorb- .ers-and Supplementary Springs; and I do declare the followin to be a full, clear, and exact descriptiono lillfllIlVlltlOIl, such. as

will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to new and'useful improvements in shock absorbers and my ob- With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement ofparts as will be hereinafter referred to and more'particularly pointed out in the specification and claims. j In the accompanying drawing forming a part of this application-.-Figure 1 is a fragmentary rea'relevationpf a vehicle having" a shockabsorbereconstriitited in accordance with my i'nventionapplied thereto; Fig. 2 is an enlarged detail section therethrough; and, Fig. 3 is a section'as seen on line 3-f-3 ofFig.2'.

design and construction for transversely -ex- I tending use.

' My proved shock absorber coiiperates, I as stated above with thisparticlilar form ofspring and in carrying out the idea I provide an angular bracket 6,' one-arm of which is removably secured by means of'bolts or set screws 7 to the inner face'of the brake band housing, the opposite arm of said bracket resting flatly upon the rear axle housing, asclearly shown in Figs. 1 and 2 of the drawing. This latter arm of thebracket has a pair of spaced apart ears 8 formed at Y thelfouter end thereof, said ears extending upwardly and receiving therethrough a pintle 9. Fulcrumed on this pintle is the lower end of a bar or lever 10, said-lower end of the lever having a laterally "extending foot.

piece or the like 11 formed thereonwhich is Q designed engage and rest flatly upon the housing of? the rear axleto limit the swing ing movement :of the lever 10' in one direction. Formed integral with this arm or lever 10 intermediate the ends thereof-and projecting laterally inward therefrom is a housing or the like 12 which is square in cross, section and has the outer end thereof open. The inner faces of the side walls of. this housing are slightlychanneled longitudinally as shown at 13.} The outer end of the lofwer leaf of the spring member 5 is a bent around and secured to a short shaft or pin 14 which rotatably supports at its ends a pain of rollers 15, the latter being of such diameter as to be readily received in the housing 12. The pin on shaft 14 is also of such size as to permit the" outer faces of said rollers to contact lightly with the inner faces Y of the sidewalls of said housing and 't e latter will, therefore, form a guide and sup- .port for the outer end of the spring and at p the sameltime permit the movement of the latter with respect to" the lever. j

In view of the particular con'structionas above described it is apparent that a'play in the connection between the outer eiid of. the spring. and the lever: is necessary.- .It

will be seen that the leverlO with its housing. forms a a support Efort e outer end of'the' {spring member 5 and shav provided, an

improved construction for supporting the P 1m]; in its upright posifiomsuch meansat to the rebounding of the spring; To this end a transversely extending coil spring 16 is provided, one end coil of which is engaged, with a clamping member 17 which is secured to the spring member 5 intermediate its one end and the central portion thereof. The opposite end coil of the coil spring 16 is'engaged with an eye bolt 18 which is loosely disposed through an opening adjacent the upper end of'the lever 10. The outer threaded end of this eye bolt is engaged with a wing nut 19 which when turned home, obviously secures the spring to the lever and admits of an adjustment of the tension of said spring 16.

Inoperation, it will be appreciated that in the travel of the vehicle the body'will be forced downwardly under its weight against the tension of the spring member 5 as ruts and other obstructions in the road are met. As the body is forced downwardly against the tension of the spring member 5, the outer ends of thelatter will be forced outwardly in the housing 12 and will force the lever 10 outwardly on its fulcrum point. This outward movement of the lever 10 will of course be against the tension of the spring member 16, thus preventing an undue outward movement and upon the rebound of the spring I member 5 said lever 10 will return to its nor.- mal and upright position with force. The inward swinging movement of the lever under such conditions is limited by the engagement of the foot piece 11 thereof with the rear axle housing and the shock incident thereto will be absorbed and the rebound of stood that other forms of springs may be used for the purpose. 7 V

It will further be understood that while'I have shown in the drawing but a portion of the. vehicle and spring therefor, and disclosed but a single shock absorber in connection with one end of therein? axle spring, a pair of such absorbers is used in connection appreciable extent, thus ieacae with each spring, the same being identical ir design and construction.

From the foregoing it will be seen that I have provided a simple, inexpensiveand efficient means for carrying out the objects of the invention and while I have particularly described the elements best adapted to per form the functions set forth it is obvious that various changes in form, proportion and in the minor detalls of construction may be resorted to, Within the scope of the ap- Having thus described my invention, what I claim is:

1. In a shock absorber, the combination with an axle and a' carrying spring above the same, of a lever fulcrumed at its lower end on the axle and having an inwardly project ing housing formed intermediate the ends thereof, means for limiting the inward swinging movement of" the lever on the easing, a roller carried on the outer end of said spring and .rotat-ably received within the aforesaid housing, and a tension spring connecting an intermediate portion of said spring with the upper end of said lever.

2. The combination with a transverse vehicle axle, and a transverse spring above the same, of an L-shaped bracket hinged at its angle to said axle to swing outwardly toward the outer end thereof, the horizontal arm of said bracket resting on the axle and extending inwardly from the hinge, and the upright arm thereof rising above the outer end of the spring and having anopening, a housing projecting inwardly from the intermediate portion of said upright arm and receiving the end of the spring, an eye bolt passing through said opening and having an adjusting nut, and a substantially horizontal coiled shock absorbing spring secured at its inner end to the other sprmg and at its outer end to said eye bolt.

In testimony whereof I have hereunto set my handin presence of two subscribing Witnesses.
